.Application ,d September To all ywzoz/i i may concern:

Be it lrnow'n that l, (IuARLns W. Joinv- SON, a citizen of the UnitedStates, residing at San Francisco, in the county ol' San `Fran-- ciscoand YState oli California, have invented new and useful Improvements inFloor- Scrapers, of which the following' is a specih cation. j

Therobject oll the present invention is to provide an improved floorscraper, which can'be used by the operator in an erect position, andwithout the necessity ol his workn ing on his hands and knees, as is atpresent the practice, and will thus enable a noch longer stroke to betaken with the scraper, so that the work is performed not only withgreater convenience and ease, but also incre quickly.

A further object ol' the invention is to provide a device of thischaracter which can be readily converted into a brush.

In the accompanying drawing, Figure l is a perspective view showing` thescraper in use; Fig. 2 is a side view of the scraper handle; Fig. 3

1s a plan view of the saine, the handle beine1 omitted; Fig. 4 is across section; Fig. is

a longitudinal central section, showing also a brush attached to thedevice Fig. 6 is a perspective view of the weight detached.

eierring to the drawing, 1 indicates theframe or" the scraper, which ingeneral raseinbles the ordinary Stanley floor scraper, having a holder 2l'or the bit 3, held in said iolder by ineens oithe screw 4.

5 indicates a wooden shoe secured upon the bottoni of the holder.

In the recess behind said bit holder lorrnod by the side walls 6 isplaced a weight .7, ol lead or other heavy metal. Said weight has alongitudinal recess S to permit ol' the passage therethrough of theadjusting' screw 9, which is secured at its front end to the bit holder,and at its rear end passes through a In -the Stanley :door scraper thisscrew is adjusted longitudinally, so as to ad just the slopeol` the bit,by means ol' two one on each sideoll said post, but in my improvement lremove the l'ront nut and retain only the rear nut 11, which preventsthe bit holder moving forward. mo hold it in place against backwardmovement there is provided an elbow l2 on the post l0, through whichpasses a screw l5', the point against the end ofthe screw SpecificationLetters laten't.

l g l I' i l l i i l l l l l 1 j' I l i l l l l l l l l i r i l l l l ll l ol said screw. .l find that the screw 13 and nut li furnish a betterIneens oi adjusting the screw to prevent longitudinal moveinent thereofin either direction, as the front nut now dispensed with-wasunsatisfactory on acr'fountol its slipping on the screw. The weight alsohass'ecesses 14 in its rear side to receive the 'post l0, and a recess2? to rerilo 28 on. `the .trarne l lhe 'we ceive is also formed with atransverse hole 15, to il which is secured by screws receive an axle li7 to the side walls, and has reduced ends or trnnnions 1S to enter theapertured ends ol a yoke 19 secured at the lower end ol' the handle 20,For convenience ol' transporta tion, said handle is preferably inade intwo sections having rabbeted adjoining ends 2l secured together hy thethuinh screws 22, or in any other convenient manner.

lthe use oi' this device will he readily apprehended from the foregoingdescription. The weight 7 is rnade sutliciently heavy to cause thescraper to press against the surlace oi' thc :door with a pressure notless than that imparted thereto by the hand of the operator in the oldstyle ol' using the scraper. At the'snnie time the labor of exertingsaidpressure during,r the lmward inovenient of scraping` is removed. Sincethe operator now works in an erect position instead of on his hands andknees, he can work more rapidly and lorva longer timeI than beforewithout any nicrcase in fatigue( .f'in im portant advantage is that thelength ol the rush, For this purpose, the traine of the device isAhnn'icd with two rearwardly etxending lng-s 29, 3i), through whichscrews 23 pass into the back 2d olI the )rush 25. A screw l also screwedinto said hack through the forward end ol' the lraine.

l. A ,door scraper comprising a freine having a rear post, a shoesecured to said freine, andV slidahle one hoor, a oit holder, a bit heldtherein, inclined rearwardly andldownward, a weight on said. trame,between said frame, an adjusting Ascrew secured-to said oit holder andassing through said longitudinal perforation und also through seidyosl,L

and n nut on the reni' end of siiid screw, substantially :is described.

2.
